The twins later resurfaced as members of the mutant terrorist group known as the Upstarts, and during this time attempted, among other things, to recruit Omega Red and kill New Mutant Wolfsbane; neither effort was successful.
Later, they joined their father in fighting against the mysterious Citizen V and his V-Battalion. During this conflict, Andrea discovered that Citizen V was, in fact, Baron Helmut Zemo, then believed dead, following his decapitation by Nomad, and as a result, Andrea was quickly killed in order to keep this knowledge from being revealed.A few years later, Andreas reappeared as the Swordsman in the latest incarnation of the Thunderbolts, though his true identity was kept secret for some time.
